A
Few Measured Words About Volatility
By
Janet Ellen Hill
With
the stock market’s recent wild ride—up one day, down the next
five—we’ve been hearing a lot about volatility, which is a polite
way of referring to investors’ nervousness. Investors may think
volatility indicates a problem, but many analysts believe the
opposite: that increased volatility in the markets is a preface
to signs of a rebound.
In
layman’s terms, volatility can be likened to car insurance premiums
that increase along with the likelihood of high-risk situations,
such as an insured’s poor driving record or if the car will be
kept in an area with a regular incidence of theft.
Volatility
is measured by the Chicago Board of Options Exchange (CBOE), primarily
through the CBOE Volatility Index (VIX) and, to a lesser extent,
the CBOE Nasdaq Volatility Index (VXN) for technology stocks.
The VIX tracks the speed of stocks’ price movements in the S&P
100; the VXN tracks the same in Nasdaq 100 stocks. Both indices
take a weighted average of the estimated volatility of eight stocks
on a particular index. Both are calculated every 60 seconds over
the CBOE’s trading day, recording a great deal of fluctuation.
The
VIX is mostly affected by put activity, which is the practice
of buying 30-day index options that protect investors from losing
big in the market. When stock prices tank, investors bid on puts
to preserve their investments. Higher prices for these options
increase the level of the VIX. But purchasing these options does
not ensure a sure thing; buyers have to be careful that they don’t
obliterate a market’s move in their favor because they paid too
much for these options.
The
VIX usually fluctuates between 20 and 30 percent. This percentage
measures the level of unpredictability that the market would have
to undergo over the next month to make the current index option
prices achieve a fair market value. Anything under 20 percent
is considered low and an optimistic sign—usually time to sell.
A VIX over 30 means there’s pessimism in the market, so it’s a
good time to buy, as stock prices will be lower.
Seasoned
traders who monitor the swings and arrows of the market’s outrageous
fortunes usually pump a lot of money into stocks and index options
when the VIX is high. Conversely, when the VIX is low, it usually
indicates that investors believe the market will head higher.
This, in turn, can trigger a market selloff as these speculators
try to unload their holdings at premium prices.
In
previous market crises, the VIX has spiked high during intraday
trading, but has tended to close below 50 percent, with buyers
rushing in to capitalize on the lower stock prices. During the
peak of the 1998 market crisis, the VIX spiked as high as 60.63,
but closed only as high as 48.56. Since the terrorist attacks
in September 2001, the VIX has pretty much ended the day in the
40s. Its highest intraday spike during this period was just over
57 percent, but it had never breached a closing higher than 49.04
until this July 23, when it closed at a high of 57 percent.
July
also saw the VIX’s highest levels since after September 11. The
last time the VIX closed higher than 50 previous to this was in
November 1987, at 55. Consider that the VIX spiked to its all-time
high of 172 percent and closed just north of 150 on the Black
Monday crash in October 1987, and this summer looks positively
mild by comparison.
Historical
data has shown that wild tremors in the market precede a change
in the market’s direction. A high VIX appears just before a market rally, and a low VIX
usually augurs a slide. If this wisdom holds true, we should
see a slow rise or at least some stabilization in the market’s
levels over the next few weeks. The
late July rally helped all three major indices make minor gains
after weeks of decline.
Some
analysts say that because of these factors, the market is probably
bottoming out right now. They do, however, temper this opinion
with caution due to any further disclosures of corporate finance
malfeasance.
Bearish
naysayers, however, repeat the mantra that past performance is
no indication of future return. They argue that any value to the
VIX’s historical behavior has gone out the window since the market
is fighting too many entrenched factors that are impeding its
health, including the faltering economy, investor mistrust of
corporations, and continued fear of terrorist attacks. They contend
that too many variables at one time may make bullish optimism
premature. Some even blame 24/7 access to financial news via cable
and the Internet for enabling volatility, as people can watch
the market move in front of their eyes.
Regardless,
trying to predict the markets has always been a gamble. And as
recent events have proven, there is never any guarantee they will
move in a logical pattern, thus throwing all bets off.
